For accurate recognition next to the drive letter of the numbers.
Relays and electronic control units are generally marked in gray. Conducted within the line - it is the internal connections. They show how the relays and other electrical and electronic devices are switched between themselves and with the relay card.
The number in a black square represents the point of the relay on the relay board with fuse. Right on the designation of the relay is marked contact. For example, if the contact is indicated in the wiring 17/87, then 17 is the designation terminals on the relay board 87: this designation on the relay terminals (Control Unit).
Designation of terminals normalized DIN.
Terminal codes
Terminal 30. This terminal is always a voltage of the battery. The cable is always red or red with colored veins.
Terminal 31. Leads to weight. Wire weight, usually brown.
Terminal 15 is powered by the ignition switch. The wires are conductive only when the ignition is switched on. The cable is always green or green with colored veins.
X. terminal conducts current and only with the ignition, but the current is interrupted as soon as the starter. This ensures that only the current supply of the ignition system during start-up. All the big tokopotrebiteli are in the chain. Main beam current is also supplied from this terminal. The main beam is automatically switched on when the ignition parking.
On the wiring on separate conductors are given numbers and combinations of letters underneath. For example:
15
WS / ge
The figures show a cross-section of the conductor. The letters indicate the color of the conductor. If the designation is made up of two groups of letters separated by a slash, as in the example, the first group specifies the main color of the conductor: WS - white, the second group of letters: GE - yellow - the complementary color. As sometimes happens that different chains of the same color wires are used, it is recommended to control the combination of colors corresponding to the conductors on the connecting terminals. White wires for differences, are provided with an additional number, which is in the wiring under the letter designation of color.
